Description

Technical Field

[0001] The utility model relates to the technical field of orthopedic external fixation brackets, and more specifically to an adjustable lifting rod. Background Art

[0002] In the field of orthopedic external fixators, the lifting rod is one of the common components. However, there is a problem with the lifting rods currently used in the market, that is, they are usually fixed and cannot be adjusted. This limitation may cause some inconvenience in practical applications.

[0003] In orthopedic clinics, patients' conditions and treatment needs vary. Therefore, the adjustment and adaptability of fixed brackets are very important. Fixed-length lifting rods may not meet the specific needs of each patient, resulting in unsatisfactory treatment results or increased surgical difficulty.

[0004] For example, under different fracture sites or conditions, the lifting rod needs to be adjusted to achieve the best fixation and support effect. However, since the existing lifting rod is not adjustable, doctors may need to use multiple lifting rods of different lengths to adapt to various situations, which increases the complexity and time of the operation.

[0005] In addition, fixed-length lifting rods may limit the patient's activities and rehabilitation. The inability to flexibly adjust according to the patient's recovery status may affect the patient's quality of life and recovery process.

[0006] To this end, the present application proposes an adjustable lifting rod to solve the above-mentioned problems. Utility Model Content

[0007] In order to solve the above problems, the present application provides an adjustable lifting rod.

[0008] The adjustable lifting rod provided in this application adopts the following technical solution:

[0009] An adjustable lifting rod, comprising:

[0010] A connecting piece, the connecting piece is detachably arranged on the orthopedic external fixation bracket, the connecting piece is provided with a connecting track, a sleeve is rotatably arranged in the connecting track, the sleeve passes through the connecting piece, and a threaded rod is movably arranged in the sleeve;

[0011] The threaded rod is threadedly connected with an upper nut and a lower nut respectively. The upper nut fits the top of the sleeve in an initial state, and the lower nut is located below the sleeve. A spring is sleeved on the threaded rod, and the spring is located between the lower nut and the bottom of the sleeve, and the top of the spring fits the bottom of the sleeve, and the bottom of the spring fits the top of the lower nut.

[0012] Furthermore, a washer 1 with a diameter larger than the sleeve is provided at the head and tail ends thereof, and the diameter of the washer 1 is also larger than the diameters of the upper nut and the lower nut; a washer 2 is provided at the top of the lower nut, and the diameter of the washer 2 is larger than the diameter of the spring.

[0013] Through the above technical solution, washer one and washer two increase the contact area between the nut and the sleeve, and the contact area between the lower nut and the spring, respectively, thereby improving the stability of the connection.

[0014] In summary, the present application includes at least one of the following beneficial technical effects:

[0015] (1) It can improve the ease of use of the lifting rod used in the combined annular orthopedic external fixator, and can make timely adjustments based on the location and degree of injury of different patients with simple operations, thus saving time and effort, facilitating hospital surgery, and saving patients pain and possible additional costs that may be incurred later.

[0022] Example:

[0023] The following is combined with Figure 1 -2 Provide further details of this application.

[0024] The present application embodiment discloses an adjustable lifting rod, comprising:

[0025] A connecting piece 1, which is detachably arranged on the orthopedic external fixation bracket, is provided with a connecting track 2, a sleeve 3 is rotatably arranged in the connecting track 2, the sleeve 3 passes through the connecting piece 1, and a threaded rod 4 is movably arranged in the sleeve 3;

[0026] The threaded rod 4 is threadedly connected with an upper nut 5 and a lower nut 6 respectively. The upper nut 5 fits the top of the sleeve 3 in the initial state, and the lower nut 6 is located below the sleeve 3. A spring 7 is sleeved on the threaded rod 4. The spring 7 is located between the lower nut 6 and the bottom of the sleeve 3, and the top of the spring 7 fits the bottom of the sleeve 3, and the bottom of the spring 7 fits the top of the lower nut 6.

[0027] See also Figure 1 and Figure 2 The head and tail ends of the sleeve 3 are provided with washers 8 whose diameter is larger than that of the sleeve 3, and the diameter of the washer 8 is also larger than the diameters of the upper nut 5 and the lower nut 6; the top of the lower nut 6 is provided with a washer 2 9, and the diameter of the washer 2 9 is larger than the diameter of the spring 7; the washers 1 8 and 2 9 increase the contact area between the nut and the sleeve 3, and the contact area between the lower nut 6 and the spring 7, respectively, thereby improving the stability of the connection.

[0028] The implementation principle of an adjustable lifting rod in an embodiment of the present application is as follows: the connection between a fixed column and a threaded rod in the existing lifting rod design is changed to a connection between a connecting track 2, a connecting plate 1 and a threaded rod 4, so that the threaded rod 4 can move in the sleeve 3 while cooperating to form a lifting rod structure, and the sleeve 3 in the track connecting plate 1 and the threaded rod 4 can rotate, so that the sleeve 3 can be adjusted to adjust the corresponding angle while adjusting the upper nut 5 and the lower nut 6 to adjust the length of the lifting rod.
